So far this issue has only occurred while playing games. It has happened while playing League of Legends and They Are Billions, not sure if the game matters. While playing the games, my computer crashes and gives me the blue screen with the :( face and says the "WHEA_UNCORRECTABLE_ERROR" below the sad face, and makes a brrr sound through my speakers.

What I've Tried;
I updated the drivers in my GPU through windows and through GeForce Experience. There was a new driver but the crash still happened afterwards. Checked other, but not all, PC parts for drivers through the websites instead of windows. One of them being the motherboard, downloaded new Chipset/Driver. Moved to reinstalling League of Legends and repairing it, thinking it was the game causing it, crash happens. Play a different game, They Are Billions (isn't multiplayer), but it still crashed. I checked for a windows update and didn't have one. Did lite research online and multiple websites said it's probably something to with the GPU. Today I used Display Driver Uninstaller to get rid of potential old drivers, while in Safe Mode, and then redownloaded the newest driver from GeForce Experience. Crash happened. Currently on Windows 10 Home. I don't know how to access files from the crashes, if there are reports somewhere on my PC.
